Step 6. Set the flap control in its fully up position.
Step 7. Disconnect the landing flaps by first spreading and rotating the aluminium split sleeve on the
flap drive fitting. Then push in the spring loaded pins by squeezing the split sleeve.
Step 8. With the trailing edge of the flap resting on your shoulder, squeeze the split sleeve with one
hand and, holding the knurled ring in the other, push the assembly inboard until it clears the
drive tube junction. Lower the flap gently.
Step 9. Unlock the aileron push rods from central bellcrank connections.
Step 10. Remove the keep rings from the front and rear spar pins and the lower strut pin, at each side,
(total 6 rings).
Step 11. Unlock the strut block from lower box section end by removing the strut pin, using the special
tool provided.
Step 12. Unlock the rear wing spar by removing its pin.
Step 13. Unlock front wing spar by removing its pin, hold down the top of the screen to prevent damage.
Step 14. Close the door.
Step 15. Lift the left wing at its wing tip, or strut tops, so that wing strut block leaves the square box-
section end. By lifting the wing high you will first disconnect the front spar hook from its pin and
frequently the rear spar at the same time. If the rear spar does not disengage, gently rock the
wing from side to side, pulling gently and twisting it until it does.
Step 16. Pull out the wing until it stops on the stop wire. Ensure that the stop wire runs over the TOP
of the aileron operating push tube before folding back the wing.
Step 17. Draw back the wing away from the fuselage until the movement is stopped by the stop ring on
the slide tube.
Step 18. Rotate the wing into a vertical position - underside of the wing to the front; trailing edge down.
Always hold the wing tip higher than the root to prevent damage to the door and fuselage with the
spars' ends.
Step
19.Carry the wing tip back into a position parallel to the fuselage. If the wing has been supported
at the strut tops, it will be necessary to set it down and pick it up again by its tip for the next
step. During this operation, ensure that the wing cannot tip forwards by walking your hands
along the leading edge to the tip.
Note that the aircraft will tip back upon folding the second wing.
Step 20. Separate the Velcro for 2 or 3 inches (50 to 75 mm) along the aileron root at a point where the
support bracket meets it.
Step 21. Place the wing trailing edge onto the retainer bracket on the tail.
Step 22. Remove the pin from the top of each jury strut.
Step 23. Rotate the jury struts carefully so that they lie parallel and next to each other.
Step 24. Undo the inboard zip on the wing’s lower surface, adjacent to the jury struts.
